also be employed an' incinerator inwhich the collected refuse maybe destroyed burning." The incineratoris made-in a compact tormfandis relatively light in weight, so that it may be placed in a sink or other convenient place wlienf utilized as a "garbage receptacle," and easily carried placed upon a heater orstove when it is desired to burn the garbage'which has collected within the incinerator? Further objects of the invention are to provide'a simple and 'efiicient structure which maybe manufacturedat aminimum cost, so that itwill be Withinthe reach of persons of ordinary means; to provide a device in which the garbage s burned to anashand in which all" odors of the burning garbage or other refuse are eliminated to provide "a device which issubstantially air tight when used as a garbage receptacleor as an incinerator, so that" contagious germs, fl es 'or other 111 sects will not" be attracted by the garbage and obnoxious odors" will not" pollute the air of'the kitchen or 'roomfin which the device is located; and to provide a device in which the garbage maybe burned afteneach meal, or" at" regular frequent intervals, thereby eliminating the annoyance and inconvenience resulting from collectors gathering the garbageiat long intervals;

The above andother objects of my invention are" obtained by the structure described inthe followingspecification and illustrated in the accompanying drawings, and where Figure 1 is elevation'alview of irnproved incinerator; the' samebeing illus trated as located upon astove, only so much of the stoveand thfe'fiile orgipethereof being shownias is necessaryto' isclose the appli "cation of the incinerator thereto; v

Fig. 2 is a top plan View of the structure shown in Fig. 1.

Fig. Sis a vertical sectional View taken centrally through the incinerator.

Fig. 4 is an elevational rear View of the incinerator.

Referring to the drawings wherein like numerals represent like parts in the several views, 10 designates my incinerator which;

as shown inFigsjl and Q may" be mounted over one of the 'holes inthe top of a'stoiie 11 hav ng" a stove pipesection 12, inthe present instance; the stove being shown niore or less conventionally as it forms nojpart of my in vention. It is'to'be understood that the'incin'erator' may be used in combination with any form of heater apparatiis, such, for'in stance, as a coal, gas, electric oroil stove.

The inciheratbrlO has a body portion 13 composed of sheet metal and comprising in thepresent instance, an open ended receptacle, cylindricalin cross-section. The body portion 13 is provided along its top edge with anexternal wirebead 1 1, while its lower end is providedwith an internal wire bead' lf H p ltfdesignates thebottom of the incine'i ator which formsa grate upon whichltlie or other refuse is burned. This bottom 16 is in the forlnof anini erted 131m. nel haying a conical body portion andia stem portion 17 extending from the apex ofthe conical portion upwardly and cen trally'of theincinerator. The bottom por tion 16 together with the stein 17 areprovided with perforations or openingsover their entire surfaces, these openings or perforations being of each size as to preterit the'garbage from falling through the 'bot tom ofthe incinerator, but, atthe same time, permitting a draft upwardly throil h the garbage Within the receptacle. The toads 16 is preferably formed of sheet metal; so thatit may be producedatfa minilnunic st and is relatively light in weight: Tie diaineter of the open end of thefbotton 16 is substantially [the ame as the internal diameter of the body portion 13 of theincineratonso that it may rest upon the flange orwire bead 15. r V 7 The incinerator 10 is jproiiided (with? a" as'in theforniofan elbowso a's'to permit the incinerator to be placed over one of the side holes of the stove 11, but it is to be understood that the flue pipe may extend radially from the body portion of the 111- cinerator when it is desired to place the device over a stove hole which is immediately in front of the stove pipe.

19 designates a lid or cover which, in the present instance, is disclosed as having a depending flange 20 adapted to fit snugly within the open end of the receptacle, as shown in Fig. 3, so as to prevent the escape of obnoxious odors, fumes or smoke from the incinerator and prevent flies, insects, and the like, from gaining access to the interior thereof. The lid is provided with a handle 21 to permit of its ready removal from the incinerator. lVhen the flue pipe 18 is not connected tothe pipe of the stove, it is closed by means of a cover 22 which is similar in structure to the lid or cover 19 heretofore described. To permit the incinerator to be readily lifted to and from the stove, it is provided with a pair of diametrically disposed handles 23, which may be of any suitable or approved type, those shown in the drawings being by way of illustration only.

When the incinerator 10 is used as a receptacle for receiving garbage, it is set aside in some convenient place, with the covers 19 and 22 over its top and flue pipe, as shown in Figs. 3 and 4:, and, preferably, it is set upon a shallow pan 24:, as shown in Fig. 3, so that if any wet garbage is placed in the incinerator, the pan will catch and hold any drippings resulting therefrom. When it is desired to burn the garbage which is collected within the receptacle, the incinerator is removed from the shallow pan 24 and placed upon the stove immediately over one of the stove holes, and the flue pipe 18 of the incinerator is connected up with the stove pipe 12 as shown in Figs. 1 and 2. The stove pipe has a damper 25 which is located immediately beneath the point at which the flue pipe of the incinerator is connected with the stove pipe, and this damper is turned into shut-off position during the burning of the garbage, so that a direct draft is obtained through the incinerator, and that portion of the stove-pipe above the damper.

During the incinerating operation, the heated gases and products of combustion from the fire in the stove over which the device is located pass upwardly through the grate or bottom 16 and dry and burn the garbage thereon. As the grate is in the form of a cone, there is a tendency for the garbage to move outwardly toward the walls of the receptacle leaving the garbage above the central portion of the grate loosely packed and thus permitting of a central draft opening through the receptacle and the likelihood of the grate becoming clogged by the packing of the garbage is eliminated. The stem or perforated pipe 17 provides a centrally disposed passageway or flue which also serves to maintain a draft opening through the garbage, and this is of particular advantage when the garbage is wet, and, therefore tends to pack. By the arrangement just described, the gases pass upwardly through the bottom of the grate and heat the garbage thereon to the point of combustion, and thus cause consumption of the same. Some of the gases, or heated proclucts of combustion, pass into the stem 17 and are drawn or forced by the draft obtaining through the flue pipe 18 in the Stovepipe 11 through the garbage. Thus the garbage in the upper portion of the can is dried out as the mass of the garbage gradually sinks in the receptacle, due to the burning of the garbage in the bottom of the incinerator, when the upper portion of the garbage reaches the bottom of the incinerator, it is in condition to be burned to an ash. 1

It will be noted that my device comprises but a relatively few number of parts which may be constructed of sheet metal, and which are, therefore, relatively light so that the incinerator may be readily placed upon and removed from a position over the stove-hole of a heater. The device may be manufactured at a relatively low cost, so that it may go into universaluse in the homes of people in moderate circumstances. 1

It is, of course, obvious that my invention is susceptible of various modifications and changes which would be within the spirit of the invention without departing from the scope of the following claims.

What I claim is:

1. In an incinerator, a portable open-ended casing, a flue opening in said casing, an internal beaded flange adjacent to the bottom edge of said casing, an inverted funnel shaped bottom detachably supported by said flange, said bottom having a central draft opening, the bottom and draft opening being perforated substantially throughout their entire surfaces.

2. The combination in a portable incinerator of a casing having means for connecting it to a draft pipe and an open lower end adapted to be brought into communication with the stove opening, an inverted funnel shaped structure adapted to be detachably supported within the receptacle near its lower end, said structure perforated substantially throughout its entire surface and a detachable imperforate cover for said lower end whereby said receptacle may be used as a garbage receiver when not in use as an incinerator.

3. In comblnation a heater, a stove. pipe for said heater, a damper 1n said pipe and a portable incinerator adapted to be placed upon or removed from'said heater, said incinerator comprising a portable open-ended casing, a flue opening insaid casing adapted to be connected to the stove pipe above said damper, a foraminated inverted funnel shaped structure adapted to form a bottom for said casing, said funnel shaped structure having a central draft passage- Way.

4. In combination, a heater, a stove pipe for said heater, a damper in said pipe and a portable incinerator adapted to be placed upon and removed from the heater, said incinerator comprising a combustion chamber having an open lower end adapted to be brought into communication with the opening on the heater, a flue pipe adapted to be connected to the stove pipe above said damper, a detachable cover for the upper end of said chamber, a bottom for the lower end comprising an inverted funnel shaped structure supported solely by inwardly projecting means at the bottom of the chamber. 7 In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
